[PATCH v3 0/6] vfio: type1: support for ARM SMMUS with VFIO_IOMMU_TYPE1

[Antonios Motakis <a.motakis-lrHrjnjw1UfHK3s98zE1ajGjJy/sRE9J@public.gmane.org>]

This patch series makes the VFIO_IOMMU_TYPE1 driver buildable on ARM, so it
may be used with ARM SMMUs. It also adds support for the IOMMU_NOEXEC flag
supported by SMMUs adhering to the ARM SMMU specification so the VFIO user can
specify whether the target memory can be executed by the device behind the
SMMU.

This applies on top of the branch 'next' by Joerg Roedel available at
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git

Changes from v2:
 - Rebased on latest iommu/next branch by Joerg Roedel
Changes from v1:
 - Bugfixes and corrected some typos
 - Use enum for VFIO IOMMU driver capabilities

Antonios Motakis (6):
  vfio: implement iommu driver capabilities with an enum
  vfio: type1: support for ARM SMMUs
  vfio: introduce the VFIO_DMA_MAP_FLAG_NOEXEC flag
  vfio: type1: replace domain wide protection flags with supported
    capabilities
  vfio: type1: replace vfio_domains_have_iommu_cache with generic
    function
  vfio: type1: implement the VFIO_DMA_MAP_FLAG_NOEXEC flag
